Specification of Letters Patent.

Patented March 16, 1909.

Application med July 13,1908. semi No. 443,293.

To all whom it may con-cern:

Be it known that we, ALFRED lil. Him- PHREY, a citizen of the United States, residing at the city of New York, county of New York, State of New York, and FREDERICK J. HUMPHREY and REGINALD WRIGHT, citizens of the United States, residing at the city of Kalamazoo, county of Kalamazoo, State of Michigan, have invented certain new and useful Improvements in Gas-Lamps, of which the following is a specification.

This invention relates to improvements in gas lamps.

The present invention relates particularly to improvements in gas lamps such as illustrat-ed in United States Letters Fatent No. 841,323, granted January 15, 1907, to Alfred H. Humphrey, and is an adaptation of, and in some respects, an improvement upon the structure there illustrated.

T he main objects of this invention are: rst, to provide in a gas lamp having inverted burners, means Yfor preventing the fouling of the air supplied to the burners by the products of combustion; second, to provide in a lan'ip having inverted burners means for protecting the burners from dust, lint, insects and the like 3 third, to pro-vide in a gas lamp having inverted burners an improved arrangement of the burners whereby they are completely accessible for adjuste ment; fourth, to provide in a gas lamp having inverted burners an improved mantle support or holder; fifth, to provide in' a gas lamp a guard for the mantles g sixth, to provide in a gas lamp an improved construction and arrangement of the parts whereby they may be readily assembled and are conveniently arranged for assembling.

Further objects, and objects relating to i structural details, will definitely appear from the detailed description to follow.

live accomplish the objects of our invention by the devices and. means described in the followinv' specification.

T he invention'is clearly defined and pointed out in the claims.

A structure embodying the features of our invention is clearly illustrated in the accompanying drawing, forming a part of this specification, in which:

Figure 1 is a vertical section of a structure embodying the features of our invention, the gas delivery pipe and the valve casing being shown in full lines. Fig. 2 is a horizontal section taken on a line corresponding to line 2-2 of Fig. 1. Fig. 3 is a detail vertical section taken on a line corresponding to line 3 8 of Fig.' 1. Fig. Ll is a detail vertical section taken on a line corresponding to line 44 vof Fig. 3, showing details of the means for securing the mantle holder and air guide plate in position.

Fig. 7 is a detail perspective view showing the lower end of the chimney, mantle holder pand mantle holder support in their open position, the parts being broken away to hetter show their form and relation. FiO. 8 is a perspective view of the mantle plate locking ring 51. Fig. 9 is a detail vertical section corresponding to that of Fig. 8, of a modification in which the supporting vrods for the mantle support are omitted. Fig. 1() is a side elevation of the support or guard for the mantle holder with the mantle holder therein disengaged from the lamp, a portion of the guard being broken away to show the arrangement of the parts.

Referring to the drawing, the gas supply pipe 1 is preferably provided with a T- coupling 2 from which the arms 3 and et depend, the arm 4 being a dummy. At the ower end of the arm 3 is a valve casing 5, which is connected to the gas delivery ring 6 by the coupling section 7. Through the ring we arrange the chimney 8 which is provided with a iiange 9 at its lower end having a douniwardly-projecting portion 10. The mixing tubes 11 of the burners are arranged through the ange 9 so that the burner tips 12 are below the flange and within the downwardly-projecting portion 10 thereof. These parts are substantially the same as those shown and described in my patent of Janu- 'ary 15, 1907, hereinbefore referred to.

We preferably provide the chimney with a chimney casing which is secured in a spaced relation to the chimney by means of the studs 14 and rivets 15, and the spacing lugs 16 toward the upper end of the chimney casing, which are preferably formed by punching in parts of the chimney casing, as illustrated. The chimney casing is open at its upper and lower ends, this arrangement of the chimney and casing being substantially the same as that shown, described and claimed `in the application for Letters atent of Alfred H. Humphrey, filed May 15, 1907, Serial No. 373,323. The chimney casing is provided with an outwardly-projecting Hangs 17 at its lower end through which the burner tubes are arranged. This chimney casing in operation serves tei-prevent the radiation of heat from the chimney, and also causes a circulation of air to set up through the chimney casing, thereby drawing the air across the burner tubes to assist in keeping the same cool.

The valve casing is provided with a downwardly-projecting pin 13, which is arranged through the flange of the chimney casing and assists in holding the parts in position. On the upper end of the chimney casing is a ringlile support 19 which is provided with openings through which the arms 3 and 4 ofthe gas supply pipe are arranged. 0n the arms 3 and 4 we arrange collars 20, which are adjustably 'secured upon the arms by means of the set screws 21. These collars,

'engaging the supporting ring very effectively support the chimney casing, and, through its connection to the chimney, the chimney and connected parts.

We preferably provide an outer casing 22 which embraces the upper ends of the burner k tube, the gas delivery ring, and chimney casing. This outer casing is open at the top for the escape of the products of combustion, and is also open at the bottom for the inlet of air, it preferably having openings 23 formed therein. Above the outer casing is a deflector 24. This is mounted upon the delivery pipe and connected to the casing by means of the straps 25, so that the outer casing may be adjusted when access is desired to the burner tubes.

A support 26 'is provided for holding the casing in its elevated position. This support is pivotally mounted upon the arm 4. The globe 27 is carried by the globe-supporting band 23 and provided with a hinge member 29 at one side. The hinge member 30 preferably depends from the valve casing 5. The globe-supporting band is secured in its closed position by means of a spring pin 31, which is adapted to engage a slot in the bracket 34, which is provided for the purpose, the bracket being arranged oppositely of the hinge. This bracket is mounted on an upwardly and outwardly-projecting -flange 35 carried on the chimney flange. This flange forms a partition between the chamber above the chimney :Gange and the parts below and within the globe, it being provided with openings 36 for the admission of air to the globe from the chamber within the .lamp casing, the air passing through these openings to the burners below the chimney flange.

We preferably provide a hook 37 for securing the globe in its open position, the hook being adapted to engage in the notch 37 provided in the hinge member 29. The Vobject of this is to prevent the swinging cf the globe andto hold it out ofthe way, when it is desired to manipulate the burners or mantles.

The pilot burner 38 is arranged through burners. VJe have not illustrated the details of the valve mechanism herein, as it forms no part of this invention.

The burner tubes 11 are arranged to open into an air chamber, which is preferably mounted on the under side of the gas delivery ring, the rear wall 39 of the chamber bcing preferably spaced from the chamber casing, the burner tubes being arranged through the bottom wall 40. The inner wall 39 is preferably provided with a flange 41 on its upper edge through which the delivery nozzles 42 for the gas delivery ring 6 are threaded, thereby securing the chamber walls in place. As the details of these nozzles will be readily understood, they are not here illustrated.

The outer wall 43 of the air chamber is preferably ring-like in form and is adapted to be slipped up over the gas delivery ring 6 when it is desired to have access to the nozzles for adjustment, the lower wall 40 projecting to form a rest for this adjustable outer wall. The wall 43 is provided with air j inlets preferably in the form of pipes 44 which project out through the outer casing 22 so that the air is supplied to the air chamber from without the casing. The object of this is to prevent the fouling of the air in the supplychamber to the burners such as would result from the passage of the products of combustion to the burner tube. The lamp which we illustrate in the accompanying drawing is particularly designed by me for an out of door lamp so that it is subjected to wind and draft which might possibly cause the products from the chimney to pass down through the outer casing and thus to the burners, but by taking the air from the oufside of the casing, this is effectively prevented.

`We preferably provide the air inlet 44 with chamber from dust and particles Heating in the air, such as lint and the like where the lamp is used in stores and factories, and also prevents the entrance of insects to the burners, thereby preventing their becoming fouled and clogged from this source. Any collection on these screens can be readily brushed QE. The outer casing 2*) is preferably provided with slots 46 adapted to receive these supply tubes, so that the outer casing can be adjusted to afford access to the parts within the same, thus making them i completely accessible.

the chimney iiange to deliver across the screens 45 which protects the air supply' giacca VWe preferably provide our improved lamp with a mantle support, consisting ofthe plate 47 having openings 48 therein adapted to ree ceive the mantle holders a9 for the mantles 50. The plate 47 not only serves as a mantle support, but also serves to direct the air to the mantles. The plate 47 is provided with an upwardly-projecting flange 51 at its outer edge, which is adapted to telescope with the downwardlj-projecting portion 10 of the chimney flange, it being preferably arranO'ed to embrace the same, as illustrated. The portion 10 of the chimney flange is provided with vertical slots 52 adapted to reA ceive the pins 53 on the plate flange 51 when the plate is telescoped with the chimney flange. We preferably secure the flange 51 by means of a locking ring 54 which is arranged within the flange and adjustably se'- cured therein by means of the pins 55 and 56, which engage suitable slots 57 provided therefor in the chimney flange, so that the locking ring can be turned to bring the bayonet slots 58 thereof into register with the slots 52 of the chimney flange to receive the pins 53 on the plate flange, so that, by turning the ring, the pins are engaged by the slots 58 thereby securing it in place. rPhe pin 56 preferably projects to form a finger piece for the adjustment of the locking ring. By this means, we are enabled to support the plate 47 at a plurality of points which `we find to be of very great advantage as it prevents the sagging or warping of the plate on account of the excessive heat of the burners to which it is subjected. The plate 47 is preferably supported, when disengaged from the chimney', by means of the rods 59 which are arranged in the sleeves 60 carried by the chimney flange. The upper endsy of the sleeves are preferably arranged through the flange on the chimney casing, see Fig. 3, so that the sleeves are very rigidly supported.

T he supporting rods are arranged to recprocate within the gas delivery ring, that is, they pass through the ring when adjusted to their upper position so that rods of considerable length may be used, thus allowing the plate 47 to drop down so that it is entirely out of the way of the operator in adjusting or cleaning the burners, and freeaccess is had foradequately adjusting the inantles. The rods effectively support the mantle plate so that it does not swing orturn while the operator is at work in adjusting the mantles,and also serve to guide the plate into its proper operative position. live preferably provide for use in this connection a cup-like guard 61 which is adapted. to einu brace the flange of the mantle plate 47, being preferably provided with bayonet slots 62 adapted to engage the pins 53 on the mantle holder so that the mantle holder and guard are held in proper relation and the guard may disengaged from its chimney. This guard is especially desirable for use when the supporting rods 59 are omitted, as it can be attached to the mantle support and the mantle with this support set down in any convenient place for the adjustment of the inantles, or if it should be desired to have access to the burners. This guard is,l however, desirable for use in connection with the supporting rods, and particularly in out of door lamps, as the mantles are thereby protected from wind, which might destroy them. Also they are so guarded that it is unlikely that the workman in cleaning the lamp, or renev;L ingthe mantles or the like, will accidentally break the same, as by hitting with a tool or the like. Also, the mantles may be burned off inV this guard, the saine being taken to any convenient place for the purpose, as, for instance, in a dwelling or factory, the smoke and odor of the burned mantles is objectionable. A further advantage is that by use of the holder, the lamp may be cleaned and the mantles renewed much more rapidly than without it, as the `workman does not need to exercise the care to avoid breaking the inantles asis otherwise required.

By forming a guide on the mantle support and chimney, as by the slots and pins, or other equivalents, the mantles are effectively guided into proper relation to the burner tips, not only bringing them into proper position to be heated to incandescence, but also prevent their being broken by being brought into contact with the ends ofthe buners. ln Fig. 3 we indicate by dotted lines the elevated position of the outer wall 43 of the air chamber for the burners. ln this position free access may be had to the burner nozzles, as 63, see Fig. 1, where a portion of the inner wall is broken away to disclose the relation of the nozzles to the burner tubes. The outer casing is made adjustable, as stated, so that it can beadjusted te Vafford free access to the parts of the lamp above the globe. By thus formingand arranging the parts, we secure an effective support for the mantles, and properly guide the air to the burners to secure a proper combination. W' e wish to remark, however, in this connection, that separate mantle holders might be provided, if desired, the plate being desirable for use merely for the purpose of directing the air to the burners and chimney, as stated.

We have illustrated and described our imn proved lamp in detail in the form preferred by us on account of its structural simplicity and economy and the convenience with which the parts may be adjusted in use. We

are, however, aware that the structural de l understood as claiming the same broadly, as

be attached before the mantle holder is l illustrated, as well as specifically.
